Taking the bulk of the thousands of votes you cast, the Contigo Autoseal West Loop Stainless Steel Travel Mug with Easy Clean Lid has sealed up the title of Best Travel Mug, and kept it warm all day.
The Contigo earned endless amounts of praise from your comments, while the majority of your criticisms again it were fixed in the latest model. The Contigo is available in 16oz and 20oz sizes and in a variety of colors.
The Contigo is top rack dishwasher safe according to its listing, but if you find yourself needing a little extra cleaning reach or power, the Oxo Good Grips Water Bottle Cleaning Set is an easy recommendation. I originally bought this set to clean a decanter, but it works just as well on the Contigo.
While reading more about the Contigo, we noticed the newest and coolest edition to the their line, the Contigo West Loop Tea Infuser Accessory. The Tea Infuser is stainless steel, retails for just $10, fits into the Contigo Travel Mug, and has a drip cup for storage when not in use. Definitely a great addition to this mug for tea drinkers.
